Specification of Letters Patent. Patented, Apr, 244, 1911?.

Application filed August 23, 1912. Serial No. 716,650.

To all whom it may concern Be it known that I, DAVID H. FRIEND, acitizen of the United States, residing at Canton, in the county of Starkand State of Ohio, have invented new and useful Improvements inBearings, of which the following is a specification.

The general object of this invention is the provision of a bearing soconstructed as to reduce the amount of friction to a minimum, saidbearing comprising inner and outer ring members which are arranged so asto permit of the free angular movement of a shaft and which will readilyreturn to normal alinement when said shaft assumes its originalposition.

In carrying out the object of the invention generally stated above, itwill be understood, of course, that the essential features thereof aresusceptible to changes in details and structural arrangements, onepreferred and practical embodiment being shown in the accompanyingdrawings, wherein:-

Figure l is a side elevation of the bear' ings constructed in accordancewith the invention.

Fig. 2 is a ,vertical longitudinal sectional view thereoff Fig. 3 is atransverse section on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary perspective of a roller bearing spacing elementused in connection with the invention.

Fig. 5 is a view similar to Fig. 3 showing a slightly modified form.

.Referring more particularly to the accompanying drawings in which likereference characters designate similar parts, it will be seen that theinvention comprises the spaced inner. and outer ring members 10 and 11respectively, the inner ring member 10 being provided with a centraltransverse opening 12 for the reception of a shaft on an engine or othermachinery. The opposed inner faces of the ring members 10 and 11 areconcaved as indicated at 13 and are adapted to receive therebetween aplurality of bearing rollers 14 which have their bearing faces convexedas indlcated at 15 whereby the same may snugly engage the concavedsurfaces of the ring members, said rollers being of a width slightlyless than the thickness of the said ring members whereby a greaterbearing surface will be provided,

thus preventing wear upon the ring members at any one particular pointas would be the case with the original form of circular ball-bearings.

The bearing rollers 14 are maintained in spaced relation by a cage 16 inthe formof a band, arranged between the ring members 10 and 11 andformed from a section of material of I beam configuration in crosssection, to provide the cage with a web por tion having formed thereinspaced and transversely extending openings 17, in which are arranged thebearing rollers 14, with the transverse side walls of the openings 17having formed integral therewith upstanding flanges 18, the ends ofwhich are-spaced from the end walls of the openings 17, said flangesbeing shaped to conform to the convexed bearing faces of the rollers 14with which said flanges contact and prevent displacement of the rollersfrom within said opemngs.

The continuous flanges 19 of the cage 16 which are arranged at oppositeends of the web portion of the cag are each provided with alined notchesforming upstanding ears 19 at the ends of the openings 17, for contactwith the ends of the bearing rollers and coacting with the flanges 18 inpreventing displacement of the bearing rollers from within the openings17.

It will also be obvious that any angular movement of the shaft uponwhich the bearing is mounted will permit of the movement of one of therings 10 or 11 relative to the other in opposite directions to an angleof approximately thirty degrees without interfering with the operationof the bearing for by reason of the concaved surfaces 13 of said ringsand the convexed sur-' faces 15 of said rollers, the parts will at alltimes be held in operative position.

In the embodiment illustrated in Fig. 5 of the drawings, there is showna slight modification in which the inner ring member 10 is provided witha beveled opening 12 whereby said member may be readily mounted upon atapering shaft.

From the foregoing description taken in connection with the accompanyingdrawings, it will be seen that the invention contemplates providing abearing which is exceedingly simple in construction thus reducing thecost of manufacture of the same to. a minimum and which is durable andeffective in carrying out. the purpose for which it is designed.

What is claimed is In a device of the class described, rings, a seriesof rollers interposed between said rings and having convexed bearingfaces, a band interposed between said rings and having spaced openingstherein receiving said rollers, arcuate flanges formed-integral with thetransverse side walls of said openings for contact with the bearingfaces of said rollers, said flanges being of less length than saidopenings, and continuous flanges on the marginal edges of said bandhaving 1 In testimony whereof I afiix my signature 20 in presence of twowitnesses.
